The Intel® Parallel Studio XE 2016 Beta program is now available!
In this beta test, you will have early access to Intel® Parallel Studio XE 2016 products and the opportunity to provide feedback to help make our products better. Registration is easy through the pre-Beta survey site.
This suite of products brings together exciting new technologies along with improvements to Intel’s existing software development tools:
I am a beginner in linux; i am using quantum espresso software; The cluster we have at University has three types of partition short (for jobs within an hour), long (jobs within 4 days) and superlong (jobs within 10 days). each node has 8 processors; however recently when I am running a job, only the SHORT partition works properly; this is not very useful for me as I need to run longer jobs. when i run the other two (long and superlong) I get several errors: running on more than one node say : 16 processors (2 nodes) producesan error:
My program calls a function and it receives two files name that are build in for command. Its goal is read a number of mol2 files and create pdbqt files. Therefore, I create a loop in which each file mol2 file name is created pdbqt file. My part of the code is below:
I wish to use Intel MPI benchmarks for performance analysis of my mpich2 implementation. However, I'm using mpich2-1.4.1 version in my cluster. Where can I download the appropriate benchmarks for this version of mpich2? The latest version is not compatible with the mpich2 version I use.
there is a problem with the latest MPI library and multi-rail support over OFA:
I am planning to develop some code for my client, to be executed on a 3 node cluster to start. Would I require this software to be installed in each of the nodes?
My client is in the progress to procure licences for this software. However this may take a while. Will it be possible to extend the evaluation period a while longer?
Today, when I run my hybrid MPI/OPenMP application with MPIRUN on our 3-nodes Infinband Linux-PCs Cluster, the following error occurred:
/cmg/dingjun/imexLocal/imex_xsamg_dave.exe: error while loading shared libraries: libmpifort.so.12: cannot open shared object file: No such file or directory
Could you tell me how to fix it? I look forward to hearing from you.
Thanks in advance.
When I run pure OpenMP example on MIC, I find KMP_PLACE_THREADS very useful. (for example, I can benchmark using 8 cores and 3 threads on every core with "KMP_PLACE_THREADS=8c,3t,0O"
What is MPI equivalent for this? (I am running pure mpi application natively on MIC with Intel MPI)
In the documentation I see I_MPI_PIN_PROCESSOR_LIST where I can provide the list of specific processors. Is there any other way?
